词条 | Diffraction efficiency |
释义 |
Diffraction efficiency is the performance of diffractive optical elements – especially diffraction gratings – in terms of power throughput. It's a measure of how much optical power is diffracted into a designated direction compared to the power incident onto the diffractive element. If the diffracted power is designated with and the incident power with the efficiency reads Grating efficiencyIn the most common case – the diffraction efficiency of optical gratings (therefore also called grating efficiency) – there are two possibilities to specify efficiency:[1][2]
